Introspection data for some FreeDesktop components

GObject Introspection is a project for providing machine readable
introspection data of the API of C libraries. This introspection
data can be used in several different use cases, for example
automatic code generation for bindings, API verification and documentation
generation.

This package contains small pieces of introspection data for the Cairo,
FontConfig, FreeType, GL, and some XOrg libraries. They are
distributed in this package temporarily, while the original sources
do not include support for GObject Introspection. They are far from
complete and only include what is necessary for other introspection
packages to work properly.
